130dB Personal Alarm Keychain-LED Flashlight Gift for Women Teen Girls Kids Student Explorer Night Workers Emergency Human Voice Security Sirens System SOS Safety Self Defense Electronic Device (4pcs)

Just what I wanted. These can be modified to be door alarms by electrically connecting a magnetic switch across the ON button. And if you are lucky you can watch the Amazon private delivery service throw your package 20-30 ft toward your house, or just put it in your USPS box on the street and leave the door open so the high pedestrian and motor traffic can admire your clearly marked AMAZON package. Check the youtube videos of their care in delivering your package.

These are SUPER loud! You will definitely catch some attention if you had to press the "panic" button. While it is great to attach to your key ring, just know that the button may get pressed while in your purse, causing an alarm. Overall, it is great & worth the money. I gave some as gifts to important gals in my life.

gave them for xmas gifts to all girl friend and kids

works great.
